This is a set of three white, rectangular melamine trays of varying sizes, nested inside each other. Melamine is a durable, lightweight, and heat-resistant plastic material commonly used for dinnerware. These trays are designed for serving food or storing items and are suitable for both indoor and outdoor use. They are easy to clean, often dishwasher-safe, and come in various sizes and styles. Melamine trays are a practical and stylish choice for homes, restaurants, and hotels. They are break-resistant, making them a safer alternative to ceramic or glass, especially in high-traffic areas. However, they are not unbreakable and should not be used in a microwave.
